Description

Technical Field

[0001] This utility model relates to the field of VOCs incinerator technology, specifically a low-temperature double-shell VOCs incinerator. Background Technology

[0002] The core function of the low-temperature double-shell VOCs incinerator is to treat volatile organic compounds through catalytic oxidation technology, converting them into harmless substances and achieving energy conservation and emission reduction. It is suitable for treating medium and low concentration, large volume of waste gas, covering complex waste gases generated by industries such as electronics, chemicals, automobile manufacturing, and packaging printing.

[0003] However, existing equipment requires pre-filtration of VOCs entering the incinerator during actual use. Activated carbon is often needed for VOC filtration, but its adsorption efficiency is limited and it needs to be replaced. Existing activated carbon filtration equipment needs to be set up separately, and the process of replacing activated carbon is cumbersome, which reduces the efficiency of the incinerator. In view of this, we propose a low-temperature double-shell VOCs incinerator. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature double-shell VOCs incinerator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature double-shell VOCs incinerator, comprising a base, a furnace body fixedly connected to the upper outer wall of the base, a discharge port fixedly connected to the upper outer wall of the furnace body, and a feed inlet fixedly connected to the outer wall of the furnace body. The feed inlet is internally equipped with a filter assembly capable of filtering the incoming gas, the filter assembly comprising:

[0006] A pressure plate is rotatably connected to the outer wall of the feed inlet. A fixed frame is rotatably connected to the outer wall of the feed inlet. A filter plate is fixedly connected to the inner wall of the fixed frame. A pull rod is fixedly connected to the connection between the fixed frame and the feed inlet.

[0007] A fixed base is fixedly connected to the outer wall of the feed inlet near the pull rod. A locking plate is rotatably connected to the upper outer wall of the feed inlet. A locking rod is slidably connected through the outer wall of the feed inlet. A locking spring is sleeved on the outer wall of the locking rod.

[0008] Preferably, the fixed base is provided with a fixing component for fixing the pull rod. The fixing component includes a locking block, which is slidably connected to the fixed base. A fixing spring is fixedly connected to the outer wall of the locking block, a sliding rod is fixedly connected to the outer wall of the locking block, and a toothed plate is fixedly connected to the outer wall of the locking block. A gear is rotatably connected to the inner wall of the fixed base. When the fixed frame is rotated to move away from the feed inlet, the fixed frame can be fixed.

[0009] Preferably, there are two sets of the locking blocks. The outer walls of both sets of locking blocks are fixedly connected with toothed plates. The upper and lower ends of the gear mesh with the two sets of toothed plates respectively. When one set of locking blocks moves, it can drive the toothed plates to move on the gear, causing the gear to rotate. This allows the toothed plates at the other end of the gear to drive the other set of locking blocks to move, so that the locking blocks can be opened simultaneously.

[0010] Preferably, the inner wall of the fixing seat is provided with a slot, the pull rod is engaged with the slot, and the end of the locking block away from the slot is formed with an arc surface. When the pull rod contacts the arc surface of the locking block, the pull rod can push the locking block to move, and the locking block can open so that the pull rod is engaged with the slot. When the pull rod leaves the locking block, the locking block closes so that the pull rod is fixed in the slot.

[0011] Preferably, the end of the fixing spring away from the locking block is fixedly connected to the inner wall of the fixing seat, the fixing spring is sleeved on the outer wall of the slide rod, and the slide rod passes through the fixing seat and is fixedly connected to the locking block. Pulling the slide rod can cause the slide rod to move the locking block, so that the locking block can be opened at this time.

[0012] Preferably, a locking seat is fixedly connected to the upper outer wall of the feed inlet, the locking plate is slidably connected to the inner wall of the locking seat, a locking groove is provided on the outer wall of the locking plate, and the locking rod passes through the locking seat and engages with the locking groove. When the locking plate moves below the locking rod, the locking rod can pass through the locking seat and insert into the locking groove, thereby fixing the locking plate and thus fixing the locking plate to the upper outer wall of the pressure plate, and fixing the pressure plate.

[0013] Preferably, a baffle is fixedly connected to the upper outer wall of the locking rod, and the locking spring is sleeved on the outer wall of the locking rod. One end of the locking spring is fixedly connected to the baffle, and the other end of the locking spring is fixedly connected to the locking seat. When the pressure plate presses on the fixed frame, the locking spring can fix the locking rod to the locking plate, so that the locking plate can block the upper outer wall of the pressure plate, preventing the pressure plate from rotating, thereby ensuring that the pressure plate is fully fixed.

[0014] Preferably, the area of ​​the filter plate is the same as the opening size of the feed inlet, the inner wall of the pressure plate is fitted with the outer wall of the fixing frame, and the fixing frame is fitted with the inner wall of the feed inlet, so that the VOCs input from the feed inlet can be fully filtered by the activated carbon in the filter plate.

[0015] Compared with the prior art, this utility model provides a low-temperature double-shell VOCs incinerator, which has the following beneficial effects:

[0016] 1. In this low-temperature double-shell VOCs incinerator, when it is necessary to unlock the filter assembly, the locking rod can be pulled up to disengage from the locking plate and the pressure plate. At this time, the pressure plate can be rotated away from the feed inlet, and then the pull rod can be pulled to move into the fixed seat to rotate the fixed frame. At this time, the fixed frame is away from the feed inlet, which facilitates the replacement of the filter plate in the fixed frame. After replacement, the fixed frame can be rotated to lock the fixed frame with the feed inlet. After the pressure plate is rotated and pressed on the fixed frame, the new filter plate can be quickly fixed by the locking plate, which makes the incinerator more efficient.

[0017] 2. This low-temperature double-shell VOCs incinerator, when the pull rod is inserted into the fixed seat, the contact between the pull rod and the arc surface of the locking block allows the pull rod to push the locking block open, thus fixing the pull rod in the locking slot and enabling the fixed frame to be quickly fixed. When the sliding rod is pulled to open the locking block, one set of locking blocks can drive the toothed plate to rotate the gear, thereby enabling the toothed plate at the other end of the gear to drive another set of locking blocks to move, allowing the locking blocks to open simultaneously. This allows the fixed frame to be quickly unlocked, making the incinerator more efficient. Attached Figure Description

A gear 65 is rotatably connected to the inner wall of the fixed base 55. When the fixed frame 52 is rotated to move away from the feed port 4, the fixed frame 52 can be fixed, so that the filter plate 53 inside the fixed frame 52 can be replaced more easily.

[0027] In this embodiment of the utility model, there are two sets of locking blocks 61. The outer walls of both sets of locking blocks 61 are fixedly connected with toothed plates 64. The upper and lower ends of the gear 65 are respectively engaged with the two sets of toothed plates 64. When one set of locking blocks 61 moves, it can drive the toothed plates 64 to move on the gear 65, causing the gear 65 to rotate. This allows the toothed plates 64 at the other end of the gear 65 to drive the other set of locking blocks 61 to move, so that the locking blocks 61 can be opened at the same time, thereby allowing the fixed frame 52 to be unlocked and enter the feed port 4.

When the pull rod 54 contacts the arc surface of the locking block 61, the pull rod 54 can push the locking block 61 to move, so that the locking block 61 opens and the pull rod 54 is engaged with the slot. When the pull rod 54 leaves the locking block 61, the locking block 61 closes and fixes the pull rod 54 in the slot, so that the fixing frame 52 remains stable.

[0029] In this embodiment of the present invention, the end of the fixing spring 62 away from the locking block 61 is fixedly connected to the inner wall of the fixing seat 55. The fixing spring 62 is sleeved on the outer wall of the slide rod 63, and the slide rod 63 passes through the fixing seat 55 and is fixedly connected to the locking block 61. Pulling the slide rod 63 can cause the slide rod 63 to drive the locking block 61 to move, so that the locking block 61 can be opened at this time, thereby allowing the pull rod 54 to quickly leave the fixing seat 55, and the fixing frame 52 can be conveniently fixed on the feed port 4.

A locking groove is opened on the outer wall of the locking plate 56, and the locking rod 57 passes through the locking seat and engages with the locking groove. When the locking plate 56 moves below the locking rod 57, the locking rod 57 can pass through the locking seat and insert into the locking groove, so that the locking plate 56 is fixed, thereby fixing the locking plate 56 to the upper outer wall of the pressure plate 51. The pressure plate 51 is fixed, thereby fixing the filter plate 53.

[0031] In this embodiment of the utility model, a baffle is fixedly connected to the upper outer wall of the locking rod 57, and a locking spring 58 is sleeved on the outer wall of the locking rod 57.

[0033] In this invention, during use, the furnace body 2 has an outer shell made of corrosion-resistant material and an inner layer made of refractory material, effectively reducing heat loss and preventing high-temperature corrosion. The double-layer structure can integrate a heat storage body, allowing for the recovery of combustion exhaust heat via a plate heat exchanger. The furnace body 2 also contains a catalytic module for complete combustion of VOCs. When the filter assembly 5 needs to be unlocked, the locking rod 57 can be pulled to disengage from the locking plate 56, allowing the locking plate 56 to rotate and disengage from the pressure plate 51. At this point, the pressure plate 51 can be rotated to disengage from the feed inlet 4. Then, the pull rod 54 is pulled to rotate the fixing frame 52 and move the pull rod 54 into the fixing seat 55. This allows the fixing frame 52 to disengage from the feed inlet 4, facilitating the replacement of the filter plate 53 within the fixing frame 52. After replacement, the fixing frame 52 can be rotated to disengage from the feed inlet 4. 2.

When the pull rod 54 is engaged in the fixed seat 55, when the pull rod 54 contacts the arc surface of the locking block 61, the pull rod 54 can push the locking block 61 to open, so that the pull rod 54 engages with the slot, and the pull rod 54 is fixed in the slot, making the fixed frame 52 stable. When the slide rod 63 is pulled to open the locking block 61, a set of locking blocks 61 can drive the toothed plate 64 to rotate the gear 65, so that the toothed plate 64 at the other end of the gear 65 can drive another set of locking blocks 61 to move, so that the locking blocks 61 can open at the same time, so that the fixed frame 52 can be quickly unlocked and enter the feed inlet 4, making the incinerator more efficient.
